y "ennui- Ne nrrmrusronemss-MomsL To all'wkomit may concern Be itknown that I, RIQHARbT. McGee, a

citizen of the United States of America, and

'ratus whereby glass 'from a tank ma resident of Wheeling, county of Ohio, and State of West Virginia, have mvented certain new and useful Improvements in'Charging Apparatus for Glass Molds, of which the following is a specification. p v

adly to-glass This invention relates bro working apparatus, and more speclfically' to a chargmg apparatus for glass molds.

The primary. object of the inventlon is to provide improved means for delivering glass from a melting (pot ortank to a mold in which it is shape A further-object 1s 'to provide an app]:-

delivered to a blow orpress mold Wit out either ekposing the same to the airor to the chilling whichresults from the use ofv a relatively coldladle or other gathermg 1nstrument of the character commonlyemployed. a 4

A still further object of the invention is to provide means whereby charges of molten glass may be delivered to' ashaping mold in any desired condition of 1atl01ty: With these and ;other ob ects 1n vlew, the

invention resides in the features of construction, arrangement of parts and comb1- nations of elements which will hereinafter be fully described, [reference being had. to.

Referring to said drawings,-in which like designating characters distinguish like parts throughout theseveral views--- 1 l 1 indicates generally a glass tank having a I passage 2.located at a suitable pointy-in a Wall thereof.' Communicating with said passage 2 is one end ofa passage or duct 3 provided in a conduit 4 of suitable refractory material whichpreferably has a horizontal disposition, as shown.

"Said Well leads verticallyfup-' ward through a'circular upright conduit 10 whlch 1s .mclosed by a wall' ll located atv a spaced distancetherefroin to provide anv in termediate annular fire space 12 which is in open communication with the firespaee 6 hereinbefore mention'e a The duct 9 leads through a conduit 13 similar to the conduit 4 and communicates a yertic'ally disposed,'

with the lower endof cylindrical receptacle or tank 14 of relatively large diameter which is open at its'upper end, as shown. The conduit 13 is at least -part1ally surrounded by a fire space 16 which communlcates at one end with the fire spaces 6 and 12 and'at its opposite end with a fire space 15 encircling the lower portion of the walls 17 by which the receptacle 14 is defined. v i

All of the various conduitsand the walls enclosing the various fire spaces are either composed of a refractory material orhave refractory linings. a

Glass from the melting tank l flows i gravity through the passage 2 thereof and seeking in a column inthe well 8 of conduit 10 which is open at its upper end and which is designed to discharge into a cavity 18 provided in ablank forming mold, as 19, seatedupon the same time that it rises in the well 8, such glass entering said receptacle through the as 20, having .a flat- By adjustment of the various'gasburners or nozzles 7 which are suitably arranged to direct'gases into the fire spaces in 'enga ement with the various conduitsand with the lower end of the receptacle definingwalls its upper end the 'end, or mouth, of

17, any desiredde of fluidity of the glass within said con uits may be mamtained.

The fire space encircles only the lower part of the receptacle 14 so that the upper part of the latter remalns' comparatlvely cool, due to which, and also to the fact that said receptacle is '0 en to the atmosphere at said-receptacle is chi ed to a marked extent. This chilhn may be increased by providing a water jac et 22 at or adjaentto'the mouth of the receptacle,

it being'designed that the lass at said mouthshall be cooled to and e maintained in ass adj 'acent to said 0 en a semi-solid elastic state of tough rubber-like consistency. Seated upon or in the rela-J tively cool glass at the mouth'of said receptacle .is a piston or plunger 23lwhich is adapted to be depressed to displace glass in said receptacle and in the duct 9 and well 8 whereby the column of lass in the latter is actuated to rise for filing the mold 19 superposed upon the pedestal top.

he cooled glass at the top of the rece tacle adheres more .or less tenaciously to-t e walls of the receptacle, and, consequently, were the plunger made of a size to fit the receptacle walls snugly, a relatively great resistance would be ofi'ered to glass-displacing movement thereof.

that of the receptacle, as shown. Due to the tough, elastic character of the glass upon I which the plunger rests, the glass does not workable glass.

rise past the sides of the plunger when the latter is depressed, but is stretched between the lower peripheral edge of the plunger and the receptacle walls to which it adheres. other words, the cooled glass constitutes an elastic cushion-like packing which is depressed by the plunger to the extent required to displace a mold-filling quantity of As is obvious, due to the relatively large diameter of the receptacle 14, a slight downward movement of the plunger sufiices to displace the small quantity The "plunger is therefore made of a diameter materially less than estal top to shear the charge from the col-- umn. Obviously, the mold may be carried to and from? charging position by a rotary press-table of an common or preferred type or it may be in ependent of such a table.

The'plunger may besupported and actuatedin any appropriate manner. As herein shown for illustrative purposes, said plunger has a vertical stem 24 pivotallv attached to a lever 25 at a point intermediate the ends of the latter. Said lever, which has one I end pivotally mounted upon a stationary post or standard 26, may be raised and lowsower, as by a-suitably located 'ower cyliner 27 Y thepiston, rod28- of-whic connectiomwith'saidjleveni .burners .linay be so located and ad that in the conduitsmay be mamta'medatt e desired consistenc that the consistency vmay'di-fi'er at di erent points 'mwsald conduits. For instance, it mayi-be desirable to increase the fluidity of the glass adjacent to the outer end of the duct 3 and'at thelower end of the well 8 over that maintained inv other parts of said duct, so that the glass will more readily rise in said well upon actuation of the plunger. Further, it is desirable that the glass be cooled to a'readil workable plast1c condition when ejecte into the mold.

Hence the fire space 6 terminates at a suitable dlstance below the top of the pedestal, and a water cooled top 20 is provided on the latter. vided throu h which the productso'f combustion are ischarged from the various fire spaces.

The plunger 23 ma be made hollow and have means associate therewith, as shown, for passing water therethrough to provide for artificial cooling thereof to the extent required.

The foregoing description ap lies specifically to a form of apparatus designed for has pivotal and I Suitably located vents 29 are pro-v use in the manufacture of glassware in which the blank mold remains in upright position following the char g o ation- 'that is, the blank mold is 51 with the neck-mold 30 disposed in superposed relation thereto, When, however, molds are to be charged 1n reversed positions, as is sometimes necessary or desirable, it becomes necessary to introduce the charge from the to instead of through the bottom, in whic case I employ the modified form of apparatus shown in Figs. 5 and 6. In such modified form, an angularly disposed top 11 is provided on the pedestal 11, with angularly disposed extensions of the well 8 and fire space -12 extended through said to as shown respectively at 8 and 12 in 1g. 5. Said well extension 8 opens to the atmosphere at a point located in overhan 'ng relation to the charging position of t e blank mold 19 so that a charge of glass will drop from the open mouth directly into said mold through the open upper end of the latter. As is obvious, means for shearing off the quota of glass to be deposited in the mold 19 may be provided at the mouth of the well extension 8*, but since such means constitutes no,part of the present invention I have not deemed it necessary to illustrate the same.
